<h1>Discover credit card validation issue: Magento EE 1.9.1.1&mdash;1.13.1.0 and CE 1.4.2.0&mdash;1.8.1.0</h1>

<p>Magento has fixed an issue that prevented some Discover credit cards from validating properly. The issue was that certain Discover credit card number ranges were not recognized as being valid. As a result of the fix, all Discover cards should validate properly.</p>
<p>This fix applies to:</p>
<ul><li>Magento Enterprise Edition (EE) versions 1.9.1.1&ndash;1.13.1.0</li>
<li>Magento Community Edition (CE) versions 1.4.2.0&ndash;1.8.1.0</li></ul>
<!-- <p>To get a fix for the issue, <a href="http://support.magento.com" target="_blank">contact Magento Support</a> and request a patch for Support ID SUPEE-2725.</p>
